I just updated my profile, and all the commas in it disappeared. I put them back in, and they disappeared again.

Witnessed the same a few months ago when I edited my profile.

That's... pretty weird. Does it happen every time you do it?

I reinserted the commas again tonight, and it still removed them. I removed the HTML tags in case that might make a difference, but it didn't. So my profile is still commaless.

Same here, by the way. Noticed this when I tried to update my profile a couple of months ago.

I have a profile sans commas as well.

The comma issue has persisted for a long, long, LONG time for me. You can use HTML Code to get around it, though; just use ' , ' in place of commas -- that's ampersand, number sign, four, four, semicolon.

While on the topic of HTML code, you can use '   ' if you need to add consecutive non-breaking spaces in text (to push text in speech bubbles onto the next line, i.e.) -- that's ampersand, n, b, s, p, semicolon.

In other words, HTML code rules, and if you need it, here's more:

And finally, to Brad: I'm on Firefox, but I haven't checked if that's why commas disappear from profiles. The only fix I've found so far is using , in place of commas. When in doubt, use HTML.
